Charlize Theron Injured During Film Shoot

Oscar winner Charlize Theron was injured Monday in Berlin while shooting her new sci-fi film, Aeon Flux – but she was not hospitalized, and it's not clear how badly she was hurt.

The accident apparently occurred while Theron, 29, was performing her own stunts, Paramount Pictures spokeswoman Jasmine Madation tells the Associated Press. The actress's rep confirms that Theron "did sustain an injury on the set. It's a very physically demanding role."

Madation says shooting on the film has been halted to allow her to recover, but there is no word on when it will resume.

Theron slimmed down, pumped up and died her hair black for the role as the sexy title character Aeon Flux – a futuristic assassin (in a skintight suit) who is sent on a mission to kill a government leader. Based on Peter Chung's futuristic MTV animated series, the film also stars Frances McDormand, Marton Csokas and Jonny Lee Miller.

For her training, stunt coordinator Charlie Croughwell had Theron on a high-protein, low-carb diet and four-hour-a-day workouts. She also worked with Cirque du Soleil performer Terry Bartlett to learn some gymnastic moves. (After her first day, she was doing back handsprings.)

"Boy, they're killing me," Theron told reporters earlier this month about her training. "I'm like, 'Where am I?' I am doing like four to five hours a day of gymnastics and things like that."

Theron, who scored the Best Actress Oscar earlier this year for Monster, will be seen next in Head in the Clouds, a World War II drama opening Sept. 17 and costarring her real-life boyfriend, Stuart Townsend.
